Tecumseh Trail Marathon
Race Day Weather
Cool start — fast day potential, big temp swing
A cool 47°F at the start line is ideal for fast times — expect to warm up quickly once you're moving. Temps will climb significantly to 65°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.
